Description

technical field

[0001] The invention relates to the technical field of communication testing, in particular to a performance testing device for an optical module receiving end. Background technique

[0002] The optical module is composed of optoelectronic devices, functional circuits and optical interfaces. The optoelectronic devices include two parts: transmitting and receiving. Simply put, the function of the optical module is photoelectric conversion. The transmitting end converts electrical signals into optical signals. After transmission through optical fibers, receiving The end converts the optical signal into an electrical signal, and the transmitting part is: input an electrical signal with a certain code rate and process it through an internal driver chip to drive a semiconductor laser (LD) or a light-emitting diode (LED) to emit a modulated optical signal at a corresponding rate. There is an automatic optical power control circuit inside to keep the output optical ...
